I just ordered the C16-22241 from Suspa. 3-4 week lead time. Not an issue.
I have the factory inside struts at the forward bulkhead which easily lift the front of the camper. The wife is having great difficulty (impossible really) raising the rear. I was leaning towards the 40# for the rear, but that seems to be a bit much even with the solar panel on the roof. 30# in the rear seems perfect as you and others have stated.
Thanks for the "how to" pics!
Bill, the speaker lift does a good job raising the roof if you don't want to go with gas struts. They are a bit clumsy, but effective.
